Description

[Detailed description of the invention] This invention consists of laying multiple levels of horizontal endless rails at appropriate intervals in the vertical direction within the frame, and placing a large number of containers placed on each level of endless rails into the frame. By attaching it to a tow chain that runs along an endless rail using drive sprockets installed at both ends of the body, a large number of containers are rotated horizontally within the frame, and a large number of small items can be loaded into these containers. This article relates to a rotating small article storage that is effective when installed in an electronic equipment assembly factory, for example, in which the items that are needed can be stored in an organized manner and the items that are needed can be easily taken out. This will be explained in detail based on the drawings.

A frame 1 having a rectangular shape in the left-right direction has a large number of supports 1a,
It is formed by connecting an appropriate number of connecting rods 1b in the horizontal direction.

Inside the frame 1, along its outer periphery, a plurality of horizontal outer rails 2 bent into long oval shapes in the left-right direction are laid at required intervals in the vertical direction. .

Front and rear inner rails 3, 3 are laid at a slightly higher position inside the outer rail 2 of each stage, and are parallel to the straight part of the outer rail 2 at a predetermined distance in the horizontal direction.

Between both rails 2 and 3, guide groove frames 4 and 4 having a U-shaped vertical cross section are installed, which are at the same height and parallel to the straight part of the outer rail 2.

Six vertical axes 5 and 6 having heights approximately equal to the total height of the frame 1 are erected at the centers of the right and left bifurcated interiors of the frame 1, respectively.

The six shafts 5 on the right side have a horizontal circle having a diameter almost equal to the distance between the outer sides of both the front and rear guide groove frames 4, at a position approximately at the same height as the center of the upper and lower blade directions of each guide groove frame 4. A plate-shaped drive sprocket 7, and interlocking sprockets 8 that are integral with the sprocket 7 and located directly above and below, respectively.
and a driven sprocket 9 are pivotally installed.

In the frame 1, motors 10 facing downward are arranged slightly above the outer rails 2 of each stage on the right side of the six shafts 5 in a vertically staggered manner.

Starting sprocket 11 fixed to the shaft of each motor 10
is connected to the driven sprocket 9 by an endless chain 12.

A sprocket 13 similar to the driving sprocket I and an interlocking sprocket 14 integral with the driving sprocket I and similar to the interlocking sprocket 8 are pivotally mounted on the left six shafts 6.

Since both interlocking sprockets 8 and 14 are linked by an interlocking chain 15, rotation of the motor 10 causes
The circumferential drive sprockets l-7 and 13 are rotated in the same direction at a constant speed.

Reference numeral 16 designates a rectangular container for storing small articles, and is removably attached to upwardly bent pieces 17a, 17a provided on both sides of a horizontal mounting plate 17 immediately below the container.

A wheel 18.18 that can ride on the outer rail 2 is pivotally attached to the lower outer end surface of each mounting plate 17, and a rising piece 17b connected to the inner end of the mounting plate 17 is mounted on the inner rail 3. Rideable wheels 19, 19 are pivotally mounted.

Each container 16 can run by having each wheel 18, 19 ride on each of the above-mentioned rails 2, 3, respectively.
It is supported on both rails 2 and 3.

Reference numeral 20 denotes an endless traction chain in which the ends of a large number of strip-shaped connecting plates 21 are pivotally connected to each other with vertical pins 22, and a lower part of each pin 22 is fitted into the guide groove frame 4. ,
And in the half inside of both ends where the guide groove frame 4 does not exist,
A horizontal roller 23 is pivotally mounted which can engage in a recess in the outer periphery of the drive sprocket 7 or 13.

Each container 16 is connected endlessly via the mounting plate 17 at a predetermined interval by fixing key points on the lower surface of the mounting plate 17 to a traction chain 20.

In the apparatus configured as described above, when a suitable motor 10 is started, the drive sprocket 7 linked to that motor 10 rotates together with the corresponding drive sprocket 13, and both drive sprockets ? , 13, the traction chain 20 rotates in a fixed direction.

As a result, a large number of containers 16 fixed to the traction chain 20 are attached to the outer circumferential rails 2 and 3 via the mounting plate 17 at the straight part of the inner rail 3 and the outer rail 2 that is parallel to the inner rail 3. Also, in the half interior where the inner rail 3 does not exist, the inner end of each container 16 rides on the drive sprocket 1 or 13 and rotates inside the frame 1.

Therefore, by controlling the selection and stopping of the motor 10 using an electronic device (not shown), the container 16 containing desired articles is automatically moved to a predetermined article entry/exit location through the shortest distance. This can be done by stopping the conveyance.

Desired articles may be removed from the mounting plate 1T along with the container 16, or only the required number of articles may be taken out from the container 16. To store the articles in the above-mentioned apparatus, the reverse operation may be performed.

Since the device of the present invention runs the container 16 using both drive sprockets 7 and 13 provided at both ends of the frame 1,
Even if the device is long, the towing chain 20 will not be overloaded and can run smoothly.

Therefore, as shown in FIG. 1, this device is equipped with an extremely large number of containers 16 and can organize and store many types of parts. If a vacant space is provided, articles can be taken in and out of all the containers 16, so that the limited floor space of the factory can be used effectively.

In addition, since the 16 groups of containers in each tier can be run independently, goods in each tier can be loaded and unloaded at the same time. This greatly contributes to improving production efficiency.
